Porquê comprar Bitcoin(BTC)?

O que é Bitcoin? O nascimento do ouro digital descentralizado
A Bitcoin (BTC) foi introduzida em 2008 por Satoshi Nakamoto e lançada oficialmente em 2009 como a primeira criptomoeda descentralizada do mundo. Permite pagamentos eletrónicos peer-to-peer sem intermediários como bancos ou governos. Todas as transações são registadas numa blockchain pública, garantindo transparência e segurança.
Como é que a Bitcoin funciona? Consenso PoW e tecnologia de blockchain
A Bitcoin funciona com um mecanismo de consenso de Prova de Trabalho (PoW). Quando Alice quer enviar 1 BTC para Bob, os mineradores competem para resolver problemas matemáticos complexos. O primeiro a resolvê-lo ganha novos bitcoins como recompensa do bloco e regista a transação na blockchain. Este sistema assegura a segurança da rede, mas resulta num elevado consumo de energia e numa maior dificuldade de extração.
Oferta de Bitcoin e mecanismo de halving
A oferta de Bitcoin está estritamente limitada a 21 milhões de moedas, o que a torna absolutamente escassa. De quatro em quatro anos, um evento de "halving" reduz a recompensa do bloco para os mineradores, abrandando a criação de novas bitcoins. Isto reforça as propriedades anti-inflacionárias da Bitcoin e é um fator chave para a valorização do seu preço a longo prazo. Até ao final de 2024, foram extraídas mais de 19,7 milhões de bitcoins.
Histórico de preços e impacto no mercado
A Bitcoin começou praticamente sem valor, atingindo $20,000 in 2017 and hitting new highs above $60 000 em 2021. Tem registado uma volatilidade extrema - como o famoso "Bitcoin Pizza Day", que marcou a sua primeira utilização comercial. Apesar de, no passado, ter sido considerada uma bolha ou uma fraude, a crescente adoção institucional e generalizada fez com que o seu valor de mercado ultrapassasse 1 bilião de dólares.
Razões e riscos para investir em Bitcoin
Proteção contra a inflação e armazenamento de valor: a oferta fixa e os eventos de redução para metade fazem da Bitcoin um ouro digital e um potencial ativo de refúgio seguro. Alta liquidez: a BTC é negociada em todas as principais exchanges, permitindo uma fácil alocação de carteira. Descentralização e autonomia: não é controlada por uma única entidade; os utilizadores têm controlo total sobre os seus ativos. Técnica e riscos regulamentares: elevada volatilidade, regulamentos pouco claros, preocupações ambientais decorrentes da exploração mineira e utilidade de pagamento limitada.
Pontos de vista céticos e perspetivas alternativas
Apesar da sua natureza revolucionária, a eficiência da Bitcoin como instrumento de pagamento é baixa e os riscos regulamentares continuam a ser significativos. Alguns especialistas veem a Bitcoin mais como um ativo especulativo do que como uma reserva de valor estável. Os investidores devem avaliar cuidadosamente a sua tolerância ao risco.

$BTC  August 3 BTC price action analysis
Review of yesterday’s overall trend: After opening, the market continued to fall, hitting a low at 1820. It then rebounded and surged up to 1883. In the afternoon it weakened again and moved lower; by evening it fell back to 1848 and stabilized. After a brief range-bound consolidation, it rebounded again and repaired.
Today’s open continued yesterday’s rebound momentum and pushed higher. In the early session it spiked to 1898, briefly breaking above the upper Bollinger Band on the 1-hour chart. However, this breakout lacked real bullish momentum. It was a typical “pump and lure” move: price quickly came under pressure and pulled back, with sustained selling in the morning driving the low down to 1849.
From the technical board: the 1-hour Bollinger Bands are generally opening downward, and the bearish trend is clear. Current price is still trading below the Bollinger middle band, so the weak structure remains. Going forward, continue to look for downside pullbacks in line with the trend.
Resistance: 1880-1920
Support: 1840-1800

What really caught my attention is that the price kept probing at higher levels repeatedly, yet never managed to take the key level away. A few pushes upward looked lively, but the follow-through couldn’t keep up. Details like this are often more worth focusing on than the surface-level rise.
I chose a short position around 56.00. After opening the trade, I didn’t rush to expand my judgment; I just observed whether the rebound would continue. As a result, the price gradually returned to 52.99, with the current performance at +101.61%. This shows that the wait wasn’t wasted.
When intraday volatility amplifies, it’s easiest to get thrown off by short-term pulls. My approach is simple: once profit shows up, I prioritize protecting it, so the space that’s already been released doesn’t end up under renewed pressure.
Understanding the change matters more than chasing the move. Missing this wave is fine—trading isn’t about a single outcome; it’s about staying clear-headed over the long run.

In the past couple of days, I’ve been chatting with friends in the circle: has crypto already died?
Let me analyze it for you from a few angles:
First, the conclusion: the consensus across countries around Bitcoin can’t “die.” It’s mostly altcoins that are dead—just going from a wild party down into a deep adjustment.
In October 2025, total market value surged to about 4.27 trillion, and now it has fallen back to around 2.2 trillion—down by half. BTC pulled back from 126k to around 63k, while dominance spiked to 58.5%—clearly, funds are moving into risk aversion. ETH has been ranging between $1,850 and $1,880, with weaker performance. Altcoins are even worse: the Altseason Index is stuck at 55-69, far from 75. Most mid- and small-cap coins have seen liquidity dry up, and the narrative has cooled off.
The macro backdrop isn’t helping either. The Federal Reserve kept interest rates at 3.50%-3.75% in July, and there were also 3 votes against raising rates—expectations of “higher for longer” are weighing on risk assets. ETFs may have cumulative inflows, but there’s been choppy in-and-out recently, and institutions remain cautious.
This isn’t death—it’s a typical cyclical cooling: speculative enthusiasm has faded, capital is concentrating into Bitcoin, and altcoins are being massively cleared out. The infrastructure is still there, the trillion-level scale is still there, and institutional channels are still there. What truly “died” is the kind of nationwide FOMO seen back in 2025.
In the short term, especially in August, it could still churn and even dip further—don’t rush to bottom-fish. For the medium to long term, whether it can restart depends on whether rates turn and whether new catalysts and narrative space emerge. You can be pessimistic about sentiment, but the data will speak— the market hasn’t died; it’s just hibernating. Wait patiently—being patient matters more than mindlessly catching falling knives.
Personally, I believe crypto hasn’t died. After this round of reshuffling, there will definitely be an even bigger narrative waiting for us—just that it will be led more by compliant institutions. The logic behind picking tokens before will all be broken, so I’m still bullish.
